Abstract

In this paper, a series of high performing PIT MgB2 strands have been prepared. Transport voltage-current measurements were performed to determine the effects of C doping and strand geometry such as filament numbers. The best Jc for our samples was 1.0 × 105 A/cm2 at 4.2 K, 7 T, for a strand using B powder with 3% C addition. The current transfer length (CTL) was also measured for MgB2 short wires with Nb chemical barrier and Monel outer sheath. The CTL ranged from 2-12 mm, and had a correlation with the filament numbers.
